Novel Chiral Bidentateη5-Cyclopentadienylphosphine Ligands: Their Asymmetric Induction at the Ruthenium(II) Center and Application in Catalysis

Abstract

As the potential for ruthenium-catalyzed reactions other than hydrogenation increases, the importance of asymmetric complexes grows. With the aid of molecular modeling, four classes of novel ruthenium(II) complexes with chiral bidentate cyclopentadienylphosphine ligands were designed and tested for asymmetric induction in a ruthenium-catalyzed reconstructive addition (see figure).
